Description

Technical Field

[0001] This utility model belongs to the field of mechanical structures, specifically relating to a transmitting antenna installation structure for a radio navigation ground transmitting equipment. Background Technology

[0002] A radio navigation system is based on the principles of radio navigation. It deploys 4-8 broadcast radio navigation base stations (collectively referred to as base stations) in a specific array on the ground, forming a broadcast radio navigation system. The interaction area formed by multiple base stations constitutes the effective area. The radio navigation system mainly consists of ground-based radio transmitting equipment, radio terminal equipment, and a control center. The ground-based transmitting equipment primarily transmits radio navigation signals, the terminal equipment receives signals from multiple ground-based transmitting equipment to achieve positioning, and the control center performs operations such as powering on / off the system and setting remote commands.

[0003] Because radio terminal equipment mostly receives radio navigation signals from ground-based transmitters while in motion, and existing ground-based radio transmitters have fixed antenna designs, the signal transmission angle of these transmitters is fixed. Figure 1 As shown, the transmitting antenna mounting structure involved in this patent specifically refers to the mounting structure between the transmitting antenna and the chassis.

[0004] Existing radio navigation transmitting antennas cannot dynamically adjust the transmission angle according to the receiving angle of the radio terminal equipment. As a result, the radio terminal equipment can only receive radio navigation signals at the receiving angle with high antenna gain. It is difficult to guarantee that the terminal equipment can receive signals from at least 4 ground transmitting equipment for a long period of time during the movement of the terminal equipment, thus failing to guarantee effective positioning in the application scenario.
